Description

Setup

How to test

Connect all ethernet interfaces to same LAN.

In "nm-connection-editor" add new "Bond" connection and configure it by adding two or more existing interfaces.

Select bonding mode "Active backup". Run ping ip.address.of.gateway and if you have IPv6 connection also: ping6 ip:address::of:gateway. Then physically disconnect and re-connect various interfaces in random (keep at least one connected).

Round-robin

Work in progress, stay tuned!

Expected Results

Using ip link show check if bonding is configured properly. "bond0" should has state "MASTER", physical ethernet interfaces should have state "SLAVE" and "master bond0" in their attributes.
